7. An apparatus, comprising: a memory; and a processing device communicably coupled to the memory, wherein the processing device to execute instruction to cause the processing device to: receive a message at a main channel used for group communication between processes executed by the processing device, the main channel comprising a fork protocol layer; identify a fork channel identifier (ID) and a fork stack ID in a header of the message; process the message with a first fork stack corresponding to the fork stack ID in the header of the message, the first fork stack comprising a subset of protocols of a main protocol stack of the main channel, the subset of protocols comprising at least a fork protocol of the fork protocol layer; and provide the message to a first fork channel corresponding to the fork channel ID, wherein the first fork channel to utilize the first fork stack to separate messages for the first fork channel from the main channel, and wherein the first fork channel and an application programming interface (API) are layered on top of a building block that is layered on to of the main channel; wherein the fork protocol layer to: implement the first fork stack utilized by the fork channel; and implement a second fork stack comprising at least two other protocols that are not part of the main protocol stack of the main channel, wherein the at least two other protocols are not implemented by the first fork stack, and wherein the second fork stack is utilized by a second fork channel to separate messages for the second fork channel from the main channel and the first fork channel.

8. The apparatus of claim 7 , wherein the processing device is further to, responsive to the message not comprising the header, process the message with the main protocol stack of the main channel.

9. The apparatus of claim 7 , wherein the processing device is further to: receive another message from the first fork channel for transmission; and add the fork channel ID and the fork stack ID to a header of the another message.

10. The apparatus of claim 7 , wherein the first fork stack comprises one or more protocols that are not part of the main protocol stack of the main channel.

11. The apparatus of claim 7 , wherein the first fork channel is created by a declarative configuration provided by a process using the main channel for group communication.

12. The apparatus of claim 7 , wherein the processing device is further to send, via the first fork channel, the message to the building block layered on top of the main channel.

13. A non-transitory machine-readable storage medium including instructions that, when accessed by a processing device, cause the processing device to: receive, by the processing device, a message at a main channel used for group communication between processes executed by the processing device, the main channel comprising a fork protocol layer; identify a fork channel identifier (ID) and a fork stack ID in a header of the message; process, by the processing device, the message with a first fork stack corresponding to the fork stack ID in the header of the message, the first fork stack comprising a subset of protocols of a main protocol stack of the main channel, the subset of protocols comprising at least a fork protocol of the fork protocol layer; and provide the message to a first fork channel corresponding to the fork channel ID, wherein the first fork channel to utilize the first fork stack to separate messages for the first fork channel from the main channel, and wherein the first fork channel and an application programming interface (API) are layered on top of a building block that is layered on top of the main channel; wherein the fork protocol layer to: implement the first fork stack utilized by the fork channel; and implement a second fork stack comprising at least two other protocols that are not part of the main protocol stack of the main channel, wherein the at least two other protocols are not implemented by the first fork stack, and wherein the second fork stack is utilized by a second fork channel to separate messages for the second fork channel from the main channel and the first fork channel.
